At a predetermined distance from an initial point, each path of a permanent way is defined by at least one signal or marking means, and a railway vehicle constrained to travel on the permanent way has: means (21) for sensing each such signal or marking means to produce a sensed signal; means (27) for measuring distance travelled from said initial point; means (26) in which is stored information describing each path in terms of the signals or marking means and their distances from said points; and means (25) for comparing a sensed signal at a measured distance with said stored information whereby to identify the path over which the vehicle is travelling.
